Question

I want to display the visualforce email template inside a panel with live preview if possible, so while I'm writing lead_name__c for example It will be bind to template where Dear recipient.lead_name__c ?? or just display it only without live preview.

What I need is, to display email preview inside custom VF page.

I believe this article on Salesforce Documentation should help you understand about VisualForce Email Template creation and live preview

Basically you just need to go to

1. Administer \ Communication Templates \ Email Templates,
2. then Click New Template button.
3. Choose Visualforce and click Next button.
4. Setup parameters like folder to store it, name, unique name, email subject, Recipient type, Related to type and click Save button.

5. => voilà: you already see you live preview saying:

   Congratulations! This is your new Visualforce Email Template.

=========================================

To show email template preview in another page, you may need to have controller property like this:

public String templateBodyPreview { get {
EmailTemplate  et = [ select id, name, body, subject, HTMLValue  from EmailTemplate where name = 'test' ]
return 'Subject: ' + et.subject + '<br/>\r\nBody preview:' + et.body;
 } private set; }

and in your visualforce page you can reference this property like

{!templateBodyPreview}
